Jerry,
I don't know what anyone else is going to use to answer this,
however I've always regarded the answer as "yes". Here's why - by
definition a small room does not exceed 800 square feet, per 3.3.21.
Let's say for argument that the room you're looking at is 800 square
feet. You would need at least two sprinklers, since the maximum
coverage for any single sprinkler cannot exceed 400 square feet, per
8.5.2.2.2. It's still a small room, if light hazard, and those rules
8.6.3.2.4.1 still apply. NFPA 13 points to allowing more than one
sprinkler in a small room in 8.6.2.1.2.1, as it suggests that the
coverage area per sprinkler is based on the square footage of the room
divided by the number of sprinklers (plural) in the room.
Seems to me you can.

Based on NFPA 13(13ed)Fig A.8.6.3.2.4 I've always thought the only time you
would exceed the 15'-0" spacing for a sprinkler is when you have a single
sprinkler in a small room.
In a situation where an L shape room 12x18 with a 4' pop out for the entry
in one of the corners along the 18' side, Could you get away with 2
sprinklers or do you need 3?
